如何预填Google表格复选框？

Question

我已经查看了" 是否可以使用谷歌电子表格中的数据'预填充谷歌表单？ "这一问题,答案中提供的代码(感谢Mogsdad)适用于文本类型的Google表单问题.我的问题是:是否可以预先填写一个复选框类型的Google表单问题？

例如,如果我有一个带有"Names"条目的现有电子表格,其中一个条目是"Fred,Barney",那么可以通过编码获得一个表单预填充,并为"Fred"和"复选框勾选" Barney"在"名称下"复选框键入Google表单问题？

谢谢,格瑞格

对于大多数其他类型,可以重复每个响应的基本模式.例如,这适用于多种选择:

            item = items[i].asMultipleChoiceItem();
            var respItem = item.createResponse(resp);

但是,复选框可能很棘手,因为它可能包含一个项目,多个项目甚至"其他"响应.将响应记录到电子表格后,它将显示为以逗号分隔的字符串; 当在表单提交事件中接收时(例如在触发器函数中),我们得到一个数组(...其中所有响应都在数组的第一项中,以逗号分隔的字符串).createResponse()checkboxItem 的方法需要一组有效的选择...所以我们可以提供一点javascript魔术:

            item = items[i].asCheckboxItem();
            // Response is a CSV string, need array
            var respArray = resp.split(/ *, */);
            var respItem = item.createResponse(respArray);

编辑:当与"其他"选项一起使用时,Google有CheckboxItems和MultipleChoiceItems的错误.允许使用这些"其他"选项,但在预填充的URL中无法正确呈现,因此它们不会以显示的形式出现.请参阅并发布问题4454.

以下是该功能的更新版本是否可以使用谷歌电子表格中的数据"预填充"谷歌表格？,更新以处理列表,多项选择和复选框响应.此版本更通用,它可以适应电子表格中的标题.奖励:如果您添加标有"预填充网址"的列,则脚本会在其中编写其生成的网址.
